#PostalPleasures Presents: How To Use UV Light To Detect Tagging On Collectable Postage #Stamps - Stamp Collecting Tools EP4
We have covered the most common tools needed by a philatelist. now lets look at the nest most common device I utilize, my ultraviolet light.
Lighthouse Brand Dual Wave Ultra Violet Lamp, Long Wave-Short Wave Switchable - https://www.amazon.com/dp/B005691KTU?...
I use the this model and highly recommend it. Amazon has a great price but the shipping is high at the moment as it comes from Europe.
Its a very versatile tool and I am sure I will overlook some uses but in this video we use the short wave feature of our UV lamp to detect tagging on 4 cent stamp featuring Abraham Lincoln issued by the US in 1965 which is available both:
Tagged - Scott Catalog #1282
Untagged - Scott Catalog #1282a
In this case they both have a minimal catalog value but in some cases tagging or lack there of can mean a significant price difference. This is truly a tool which can pay for itself.
in addition to tagging UV light can be used to detect different levels of #Florescence or #Phosphorescence in the stamp paper. It can also be used to detect color varieties of rare stamps. In particular Ultra Violet Lamps are often used in German stamp collecting
Lastly, wavelength of the UV light is important. US stamps require shortwave lights but some countries require long wave UV light. The light I use is made specifically for stamp collecting and has selectable 254 nanometer Shortwave and 380nm longwave lightbulbs.
